China’s thioacetic acid demand is close to 2,000 tons and the market concentration is high

Thioacetic acid, also known as thioacetic acid and ethylthiol acid, is an organic chemical with the chemical formula C2H4OS. Thioacetic acid is a yellow liquid with a strong mercaptan odor. Thioacetic acid is a tear gas, and its vapor has a strong irritating effect on the nose, throat and skin. After contact, irritating symptoms and signs of skin, mucous membranes, especially the eyes and upper respiratory tract will occur.

At present, the production of thioacetic acid at home and abroad has formed two mainstream processes: one is to use hydrogen sulfide as raw material, and generate thioacetic acid through the reaction of hydrogen sulfide and acetic anhydride. The process is relatively complex and dangerous. Generally, An independent device is required to prepare hydrogen sulfide; the other is to use phosphorus pentasulfide and acetic acid as raw materials, and generate thioacetic acid through the reaction of phosphorus pentasulfide and acetic acid.

Although thioacetic acid is widely used, it is mainly concentrated in the fields of pharmaceutical intermediates and flavors and fragrances. Especially in the field of pharmaceutical intermediates, the demand for thioacetic acid accounts for about 80%, and the demand in the field of pharmaceutical intermediates accounts for about 80% in recent years. Still showing a growth trend.

Affected by the epidemic and the improvement of consumer health awareness, the pharmaceutical industry represented by biotin continues to develop. As the main raw material of biotin, the demand for thioacetic acid also continues to grow. At the same time, with the development of food, cosmetics and other industries, my country’s The demand for thioacetic acid has also increased in the field of flavors and fragrances. According to the “2023-2028 thioacetic acid industry market in-depth research and investment prospect forecast analysis report released by the Industrial Research Center, China’s demand for thioacetic acid in 2022 will be close to 2,000 tons.

Thioacetic acid is a hazardous chemical and can cause great damage to the environment. In recent years, my country’s environmental protection supervision has become increasingly strict, and companies with large wastewater or waste liquid emissions have been restricted from production, thus affecting the expansion and healthy development of the thioacetic acid industry. In addition, as a hazardous chemical, thioacetic acid’s import and export trade is subject to strict supervision, which will have a certain negative impact on thioacetic acid exports, making it difficult to significantly increase the export scale of thioacetic acid.

Thioacetic acid is a niche chemical product. Coupled with the increasingly strict environmental protection policies, some companies have withdrawn from the market. At this stage, there are not many domestic thioacetic acid production companies, mainly including Huanggang Rongjin Chemical Co., Ltd. and Yumen Biotechnology Co., Ltd. Company, Huaihua Baohua Biotechnology Co., Ltd., Yancheng Liankai Chemical Co., Ltd., etc.

Industry analysts said that most companies producing thioacetic acid in China have product purity of more than 98%, and only some companies can produce it routinely. Products with a purity of over 99%. On the basis of producing 98% purity, thioacetic acid companies can actively develop products with a purity of over 99% or even higher to seize market opportunities.
